1 Claim.

The present invention relates to a vertical rotary tool support and it consists in the combinations, constructions and arrangements of parts herein described and claimed.

Generally there is provided a rotary work support which extends in a vertical plane and which is provided with novel means for moving the same to selected positions together with novel means for taking up play in the moving parts of the mechanism. Novel means is also supplied for keeping the apparatus dust free.

It is accordingly an object of the invention to provide an apparatus of the character set forth which is simple in its construction and operation and yet effective and eiiicient in use.

Another object of the invention is the provision, in a device of the character set forth, of novel means and mechanism for taking up playin Another object of the invention is the pro- Vision of novel means for moving a worm wheel which forms a part of the apparatus.

A further object of the invention 'is the provision of a device of the character set forth in which friction within the same is reduced to a minimum.

Other and further objects of the invention will become apparent from a reading of the following specification taken in conjunction with the drawings, in which:

Figure 1 is a side elevational view of an embodiment of the invention,

Figure 2 is a fragmentary sectional View taken along line 2-2 of Figure 1,

Figure 3 is a plan view of the device shown in Figure 1,

Figure 4 is a sectional view taken substantially along line 4-4 of Figure 1,

Figure 5 is a sectional view taken substantially along line 5-5 of Figure 1,

Figure 6 is a reduced end elevational view of the device shown in Figure 1,

Figure 7 is a fragmentary perspective view of the locator for adjusting the shaft,

Figure 8 is a sectional view taken along line 8-8 of Figure 3, and

Figure 9 is a plan view of the locator in assembled position with the shaft.

Referring more particularly to the drawings, there is shown therein a vertical rotary tool support comprising a base I0 which is provided with an upwardly extending vertically disposed, integrally formed plate II which is provided with a rather large opening I2 in one side thereof.

A horizontally extending opening I3 extends through the plate II and communicates vwith the opening I2 and a hollow bolt I4 is disposed in the opening I 3 and an opening I5 extends through the bolt I4 which is provided with a hollow head i6 at one end and is threadably connected with a work support Il at its other end as indicated at I8. An opening I8 is formed in the work support and registers with the opening I5 in the bolt I4.

A relatively small thrust bearing I9 surrounds the bolt I4 and is mounted in a recess 20 in one side of the plate II and is retained therein by means of the bolt head I6. A relatively large thrust bearing 2I is mounted a recess 22 upon the face of the support I'I and in a recess 23 formed in the plate II on that side thereof opposed to that containing the recess 20.

A worm wheel 24 is located in the opening I2, is revolubly mounted upon the bolt I4 and is afxed to the work support Il by means of screws 25.

The upper end of the plate I I is provided with a horizontally `extending opening 26 in which is disposed a shaft 2l to the inner end of which is aii'ixed by means of a key 28 a worm 29 which extends downwardly through an opening 30 to enmesh with the worm wheels 24. The outer end of the shaft 2l is provided with an operating handle 3| which is held thereon by a retaining nut 32. A pointer 33 is afxed to the top side of the plate II by means of a screw 34 and is adapted to coact with a dial 35 which is mounted upon the shaft 2l by a slip rit. A lock nut 35a is threadably mounted on the shaft 2l outwardly of the dial 35.

A locator member 36 is provided with a centrally disposed opening 3l through which the shaft 2l extends and the member 36 is provided with upper and lower rounded faces 38 and 39, respectively, and which t snugly in rounded recesses 40 and 4I, respectively, formed in the plate II. One end of the member 36 extends through an opening 42 formed in one side of the plate II to a point flush with the surface thereof and to this end of the member 36 there is affixed by means of screws 43 a dependent plate 44 having an arcuate slot 45 in its lower end through which extends a locking screw 46 which is threaded into the plate I I.

Thrust bearings 4'! and 48 are provided upon either side of the member 36. The bearing 4'I is provided with an adjusting nut 49 which is threadably mounted upon the shaft 2l and the bearing 48 abuts the inner end of the worm 29.

A felt dirt sealing ring 50 is interposed between the plate II and the inner face of the Work support I'I. A cap 5I encloses the bolt head I6 and the bearing I9 and is aixed to the plate II by means of screws 52. To lock the table I'I in any selected position, a lock nut 53 is threaded through the plate II and is adapted to bear against the Worm wheel 24. A plug 54 provides access to the opening 26. An opening 5ta is provided in the cap 5I in registry with the openings I5 and I8".

The table I'I is provided with calibrated indicia I'Ia on its outer face and a pointer 60 is a'ixed to the plate II by means of a screw 6I. In the face of the work table II there is provided a pair of T-slots 62 in each of which is a work bolt 63.

In operation, it will be apparent that when it is desired to move the support or table I'I, it is only necessary to move the handle 3| thereby rotating the shaft 21 and consequently the worm 29. This, in turn, will cause the rotation of the Worm Wheel 24 upon the bolt I4 and thus cause rotation of the table I1. In order t0 eliminate any possi-ble play between the worm and the worm Wheel, the

ut 46 may be loosened and the arm 44 moved in a clockwise position as viewed in Figure 1, thus i causing the shaft 2l and the Worm 29 to move into closer contact With the worm wheel 24. When the Worm 29 and the worm wheel 24 have been brought into proper relationship, the nut 46' may again be tightened. Since the dial 35 has calibrations thereon, the same may be read by means of the pointer 33 and thus a ne calculated adjustment may be made at will. With construe* tion above set forth it is possible to move the table I-'I by means of the handle 3| with a minimum of friction thus permitting the operator of the apparatus to feel the action of tools. upon the work and thus allowing him to perform a much better job at all times, the indicia Ilot` and the pointer 60 assisting greatly in this respect.

While but one form of the invention has been shown and described herein, it will be readily apparent to those skilled in the art that many minor modifications may be made Without departing from the spirit of the invention or the scope of the appended claim.

What is claimed is:

In a device of the character described including a base and a vertically extending plate, a vertically extending Work table revolubly mounted in the outer face of said plate, a worm Wheel affixed to the rear of said work table, a shaft extending substantially horizontally through said plate, a worm gear aii'ixed to said shaft and enmeshed with said worm wheel, and an operating handle for said shaft, the provision of means for adjusting the shaft and worm with respect to the worm Wheel, said means including an adjusting block revolubly mounted in said plate and having an axis of revolution perpendicular to the longitudinal axis of said shaft, said block having an opening therethrough for the revol'uble reception of said shaft therein, an arm aixed to the outer face of said block and having an arcuate slot formed adjacent its outer end, and a headed screw extending through said slot and threadably engaged in said plate.
